针对鄂尔多斯虎狼峁区长6油藏的低渗、特低渗储层、孔隙结构非均质性严重、油层横向变化大、纵向含油不均等特点,通过油藏精细研究、水驱规律分析等手段,进一步对该区进行重新认识和研究,提出一套适合本区的开发技术政策及综合治理技术措施。通过油藏工程分析,结合常规动态分析对剩余油分布规律进行研究,并结合新技术适应性的研究制定科学的开发调整方案,进行二次开发部署,达到提高最终采收率、改善油藏开发效果的目的。
In view of the characteristics of low permeability and ultra-low permeability reservoirs of Chang 6 reservoir in Huluomadian area, Ordos, the serious heterogeneity of pore structure, large horizontal variation of oil layers and unequal longitudinal oil, through the careful study of reservoirs and the analysis of waterflooding laws , To further re-understand the region and research, put forward a set of suitable development and technical policies for the region and comprehensive management of technical measures. Through the analysis of reservoir engineering, combined with the conventional dynamic analysis of the remaining oil distribution law, combined with the adaptability of new technology to develop a scientific development and adjustment programs, the second development and deployment, to improve the final recovery rate and improve reservoir development The purpose of the effect.
